Decimal separator and 4GL_NUMERIC

Hi all,
we are building an application which uses decimal numbers but something is not going as expected.

Aubit4GL version is 1.2.38, binary installation on Ubuntu 12.04 32 bit.

In detail, we tried to obtain numerical output with two decimal and comma separator with the following code:

::::::::::::::
formtest.4gl
::::::::::::::
main
DEFINE l_sai           decimal(8,2)
OPEN WINDOW w_test AT 2,1 WITH FORM "formtest"
     ATTRIBUTE(PROMPT LINE FIRST, MESSAGE LINE 2, COMMENT LINE LAST)
let l_sai = 123.45
while true
  input by name l_sai without defaults
  after input
    display by name l_sai
  end input
  sleep 1
end while
close window w_test
end main


::::::::::::::
formtest.per
::::::::::::::
DATABASE FORMONLY
SCREEN
{
xxxxxxxxxxxxxxxxxxx
Test [a        ]
xxxxxxxxxxxxxxxxxxx
}
END
ATTRIBUTES
a    = FORMONLY.l_sai;
END
INSTRUCTIONS
DELIMITERS "  "
END


 
When ran, if input is 44738, then output is

xxxxxxxxxxxxxxxxxxx
Test   44738.00
xxxxxxxxxxxxxxxxxxx

instead of 44738,00 as desidered.



We made several attempt with: 

A4GL_ALLOWCOMMAINDECIMAL=Y   (tried with or without)
A4GL_NUMERIC=,. (also tried . or , or ., or disable) 
LANG=it_IT.UTF-8 (tried with or without)

in $AUBITDIR/etc/aubitrc without any change in output, it seems these variables do not have any effect.

Any help appreciated, thanks anyone

Alessandro
